Vocal Morpher
This unique effect allows you to select two vocal phonemes and morph between them
using an LFO. Phonemes are the consonants and vowels we use in articulating speech
sounds and these sounds are very distinctive and evocative. 30 different phonemes are
available and these can be shifted up or down in pitch for even more effects.
To use the Vocal Morpher, you just select Phoneme A and Phoneme B from the list of
thirty. Now the LFO automatically morphs back and forth between the two selected
phonemes, creating interesting vocal articulations. The rate of the LFO is adjustable and
you can select between Sine, Triangle or Sawtooth waveforms. The sine and triangle
waves fade smoothly. The sawtooth wave gradually fades, then jumps abruptly back.
When the frequency of the A or B Phonemes is shifted up or down, entirely new effects
can be produced. These frequency controls can also be used to tune the phoneme
frequencies to the range of audio you are processing.
